THE ELDER AMONG YOU H H 352 Abdullah the son of Sahl went to Khaybar with Muhayysah the son of Mas'ud during time of truce. There they went about their different business. When Muhayysah returned he found that Abdullah had been murdered, and was covered in blood. He arranged for his burial and left for Medina. Abdur Rahman the son of Sahl and Muhayysah and Huwayysah the sons of Mas'ud went to the Prophet, praise and peace be upon him, and Abdur Rahman began to speak as he was the best spokesman among them. The Prophet, praise and peace be upon him, stopped him saying: 'The eldest, the eldest.' So Abdur Rahman being the youngest among the three became silent and the other two spoke to the Prophet, praise and peace be upon him, He asked: 'Do you swear to this and demand justice done to the murderer?' And he reported the whole quotation." R 352 Bukhari and Muslim with a chain up to Sahl the son of Abi Hathmah who related this.
